NIB-EJECTING PENHOLDER.

SPECIFICATION forming part of Letters Patent No. 661,910, dated November1.3, 1900.

Application filed September 27,1900. Serial No. 31,294. (Noimodel.) l ITo all whom t may concern:

3e it, known that I, FREDERIC LIONEL GRAHAM, a subject of the Queen ofGreat Britain and Ireland, residing at Nareen, in the Colony ofVictoria, Australia, have invented certain new and useful Improvementsin NibEjecting Penholders; and Ido hereby declare the following to bea'full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The object of this invention is to provide improvements in penholders ofthat class wherein the nib is ejected by the operation of a partpermanently attached to the penholder.

In carrying out my invention I avoid faults which would militare againstits extensive adoption. I avoid making it heavy, costly, clumsy, orliable to get ont of order. The upper end of the penholder is capable ofuse as a paper-knife.

To these ends, first, I make'each member of my penholder of simple anddurable construction second, the casing of the penholder is notnecessarily larger than in ordinary penholders and is of wood,vulcanite, or other material; third, the number of distinct parts in mypenholder is four, and, fourth, the assemblingof these four parts can beperformed rapidly without special tools or skilled labor.

I illustrate my invention by which the above advantages are secured inthe accompanying drawings, in Which- Figure l shows my penholder inlongitudinal section in the position assumed when the spiral spring,hereinafter referred to, has been strongly compressed and has ejectedthe nib. In the normal position of the parts in Fig. 2 the said springis compressed slightly. Fig. 2 shows in longitudinal section the partsassembled'in normal position with nib inserted; Fig. 3, the plunger withits spiral spring;

Fig. 4L, a perspective view of a part to be permanently fixed within thecasing; Fig. 5, a longitudinal section of the casing, and Fig. 6 across-section on the line w to y in Fig. 1. The plunger upper end inFig. 1 is modified in Figs. 2 and 3.' Fig. l exhibits the preferredcasing, which keeps the plunger from turning, prevents it being pushedobjectionably far when ejecting the nib, and enables lower end (indotted lines in Fig, 3) is curled up, as shown by firm lines, andslitted in any usual manner to form a nib-h0lding part e in size such aswhen slightly compressed to fit in lower end of casing a and whenfurther compressed to allow of a nib being insei-ted and held tight inthe casing, as seen in Fig. 2. Then (in order) there is on the plunger arib f, against which the back end of the nib is to abut, then a narrowspindle g, then a cylindrical or tapering curled-up portion h, adaptedto fit closely against the inner walls of the upper end of the casing,and then a flat (preferably) metal endl of the plunger, this end beingnormally exterior to the casing and preferably tapering.

k is a spiral spring slipped loosely over the spindle g. The upper endof the spring 7o abuts on the inner extremity of the upper curledportion h of the plunger, and the lower end of the spring k abu tsagainst the arc or Split ring t', which is slipped over the plunger intosuch position that the inner extremity of the rib fshall abut againstit. Each of the ends of this split ring acts as a stop. It may be calleda double-abutment ring, as the edges at each end are turned in as markedj, and it is springy-that is, can be compressed or expanded, resumingwhen free its normal diameter.l The plunger, with spring la extendingthe full length of spindle g, will pass easily into place in the' casinga, but the ring t' has to be compressed, so that it may do so. Ring 2and spring k being put in place on the plunger the whole are pushed intocasing a, the ring t' being sprung into the enlargement c from itscompressed condition and litting the same tightly, the shoulders oredges j of the ring nevertheless projecting into the bore h, so' thatthe spring la and the rib f shall abut against the said edges IOO casinga wider, longer, and better paper-` outter or blade Z is in that oaseprovided than otherwise, and the shoulder m is stopped by the slit endwhen the part e is sufficiently protruded, such stoppage being anadvantage.

The aboveeonstruetion is .that in which my: invention is best embodied;but minor details may be modied without departing from theA spirit of myimprovements.

What I claim as my invention, and desire i to secure by Letters Patentof the United States, is-

1. In a nib-ejecting penholder, the combinationwiththe hollow easinghaving near the nib endan enlargement of its-bore, and having adouble-abutment spring-ring sprung thereinto, and a Vslit in its otherend, of a spring-retracted plunger having integrally, in theorder'stated, the curled-up portion e, rib f, narrow spindle g,curled-up portion h, a shoulder fm and a paper-cutter end [,'allsubstantially as and for the vpurposes set forth.

2. In a nib-ejecting penholder the combination with the hollow easinghaving near the With a shoulder.

nib end an enlargement of its bore and having sprung thereinto a splitring i having at each end turned-in edgesj to serve as abutments, of aplunger having integrally in the order stated, the curled-up portion e,rib f, narrow spindle g, a spiral spring lo extending the full length of'the spindle and bearing against an abutment of ring t', curled-upportion h, ,and the projecting paper-cutter or blade l all substantiallyas and for the purposes set forth.

3. In a nib-ejeeting penholder, the Combination with the hollow veasinghaving near the nib end an enlargement of its bore, and having sprungthereinto a split ring 'L' having at each end turned-in edges j to serveas abutments, of aplunger having integrally in the order stated thecurled-up nib-holding portion e, the yrib f, narrow spindle g inelosedby a spiral spring, a curled-up portion `h fitting within the bore ofthe easing, and an extremity projecting from the end of the easing, allsubstantially as Aand for `the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERIC LIONEL GRAHAM.
